stimulator of interferon response cGAMP interactor 1/Stimulator of interferon genes protein in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL4523377] [GtoPdb: 2902] [UniProtKB: Q86WV6]
ChEMBL STING Biochemical [3H]cGAMP Competition Assay: The individual compounds described in the Examples herein are defined as STING agonists by (i) binding to the STING protein as evidenced by a reduction in binding of tritiated cGAMP ligand to the STING protein by at least 20% at 20 uM (concentration of compound being tested) in a STING Biochemical 13H1-cGAMP Competition Assay and (ii) demonstrating interferon production with a 6% or greater induction of IFN-β secretion at 30 uM in the THP1 cell assay (where induction caused by cGAMP at 30 uM was set at 100%).The ability of compounds to bind STING is quantified by the ability to compete with tritiated cGAMP ligand for human STING receptor membrane using a radioactive filter-binding assay. The binding assay employs STING receptor obtained from Hi-Five cell membranes overexpressing full-length HAQ STING prepared in-house and tritiated cGAMP ligand also purified in-house. B 5.41 pEC50 3873 nM EC50 US-10730849-B2. Benzo[b]thiophene compounds as STING agonists (2020)
